Compared with general-purpose reducers, precision reducers for industrial robots require short drive chains, small size, high power, light mass and easy control. A large number of reducers used in articulated robots are mainly RV reducers and harmonic drive gearboxes.

Industrial robots are widely used in the automotive industry, electrical equipment manufacturing, food processing machinery manufacturing and other industrial chain manufacturing, with the increase in the cost of manual services, the development trend of intelligent robots to replace manual services is becoming more and more significant, and the advantages of good consistency of goods manufactured by intelligent robots, high precision of assembly lines are also increasingly suffering from the high attention of manufacturers.

Strain wave harmonic drive gearbox is mainly composed of four basic components: a wave generator, flexible gear, flexible bearing and rigid gear. A harmonic reducer is a kind of gear transmission that relies on the wave generator assembled with flexible bearings to produce controlled elastic deformation of the flexible gear and meshes with the rigid gear to transmit motion and power. The advantages of the harmonic drive gearbox are explained in detail below.

The gearbox needs to withstand the force from the wind wheel and the reaction force generated by the gear transmission, which requires that the gearbox must have sufficient rigidity to withstand the force and torque, prevent deformation, and ensure the transmission quality.

The gearbox system includes gears, driveshafts, bearings and box structures. Among them, the box structure plays a supporting and sealing role in the whole system, and the probability of failure is very low. Therefore, in the gearbox, the failure mainly occurs in the gear, transmission shaft and bearing. According to statistics, gear, shaft and rolling bearing failures account for more than 90% of gearbox failures.

Gearbox is an important part widely used in the rotation of the system. It consists of two or more gears, including at least one drive gear with a certain diameter, and one smaller gear connected to the drive mechanism (electric motor, wind turbine, diesel generator, and so on).

Speed reducers primarily serve two purposes. First, they can multiply the torque generated by the input power source to increase the amount of usable work. Second, they are used to reduce the input power source speed to achieve desired output speeds. For this reason, a smaller, less expensive motor with a speed reducer may enjoy wider application fields than a larger motor without one.

The correct installation, use and maintenance of the planetary speed reducer & gearbox are important parts of guaranteeing the normal operation of the machine and equipment. How to install the motor to the planetary gearbox properly? Here are some tips for your reference.

In the family of gearboxes, the planetary speed reducer or gearbox is widely used in transmission systems such as servo motors, stepper motors and DC motors due to its small size, high efficiency, wide deceleration range and high precision. In the premise of ensuring the precision transmission, it is mainly used to reduce the speed, increase torque and reduce the inertia ratio of the loads or motors. Thus, how to choose a right planetary speed reducer or gearbox to fit a motor?
